“Please not to worry,” the 69-year-old singer said in the statement. “I am not in a life threatening condition, but I need to deal with this right away, and get some rest and medical care immediately in order to sustain and maintain my future performances.

“I promise I’ll be back,” he continued. “Unfortunately, health does not wait and it’s something even I can’t schedule around our shows. As they say, ‘We humans make plans, and God laughs.’ I love you all and will be back with you soon.”
